Abstract

240,566. Bevan, C. July 10, 1924. Moving-chamber apparatus.-The apparatus is adapted to traverse and to present the containers to measuring and filling means in contiguity with which the containers are raised to close the bottom of the measuring vessel and gradually lowered therefrom to effect the filling of the containers. In the reservoir 10 for the material rotate arms 11 sweeping the material towards a hole or holes 12 in the bottom below which rotates a disc 13 from which depend measuring vessels 14 open at each end. A rotating disc 15 forming with the disc 13 a turret carries vertically sliding holders 16 adapted to receive the canisters 17 to be filled. The rods 18 of the holders 16 rest on a fixed cam track having an ascending portion 20, a level portion 21 below the openings 12 and a descending portion 23 which is stepped to shape the material in the filled canisters. In a modification the disc 13 is dispensed with, the measuring vessels 14 being fixed to the bottom of the reservoir 10 which rotates, and fixed arms are provided within the reservoir to sweep material into the chambers 14 and to wipe excess from the tops of the vessels. The measuring vessel may be telescopic or may be fitted with detachable linings to vary the capacity. The material is supplied to the reservoir through a flexible pipe entering the top and extending nearly to the bottom of the reservoir. The bottom of the pipe is provided with a hinged flap which automatically closes when a predetermined amount of material has entered the reservoir. The cover of the machine may be connected to a fan to protect the operatives from dust. The port or ports through which the material is delivered to the measuring vessel may have a tubular guard adapted to be opened by the raising of the canister, the guard remaining closed if the canister is present. The canisters are conveyed to the machine by a conveyer 29 being fed on to a disc 31 geared to feed the canisters on to the carriers 16. Associated with the feed and with the delivery of filled canisters is a pivoted deflector 32 controlled by the cam 33 which simultaneously moves an empty canister from the disc 31 on to the turret and removes or aids in removing a filled container to the belt 30, the latter having a curved deflector 34 below which the deflector 32 moves.
